VENT-BUNG.

SPECIFICATION forming part o f Letters Patent No. 349,354, datedSeptember 21, 1886.

Application filed Deeemlzer 14, 1885. Serial No. 185,558. (No model.)

To all whom, it may concern:

Be it known that I, JOHN MEYER, a citizen of the United States, and aresident of Covington, in the county of Kenton and State of Kentucky,have invented a certain new and useful Improvement in Vent Bungs andBushings, of which the following is a specification.

My invention relates to bungs for casks. lts object is to provide aconvenient means for venting the cask.

Vith this object in view my invention consists in a hollow bung haifinga valved opening through its wall and the central opening closed by aglobe, whichl is compressed within the opening to form an air-tightjoint, the device so made forming a vent-bung.

It also consists in certain novel features and combination of partswhich relate to the economic construction and effective working ofthedevice,all of which will be first fully described in connection with theaccompanying drawings and particularly referred to, an pointed out inthe claims.

In the drawings, in which like parts are represented by similarreference-letters wherever they occur, Figure 1 is a vertical section ofa bun g and bush embodying my invention, sh owing the stopper in thesectional ligure in dotted line and in full elevation above it. Fig. 2is a detail view. of the parts, the bushing and hollow bung beinglshownin vertical section and the globe or stopper in elevation above it. Inthis view the hollow bung is made in two parts diametrically dividedinstead of in one piece, as shown in Fig. 1. Figs. 3 and 4 arediametrical sections ofmodifications of the bung shown in Figs. 1 and 2.Fig. 5 is a similar sectional view of my device adapted to close thefaucetopening.

A is a metal bushing for the bun g-hole, screwthreaded externally to bedriven into the opening in the casl; by a key or wrench applied to thekey-seats a. It is also internally threaded to receive a hollow bung, B,which is externally threaded to engage the screw-threads in the bushingA. The interior of the part B is turned or cored out, forming an annularconcave depression to form a seat for the globe stopper C, which is madeof rubber or some elastic material. The part B has also keyseats b toreceive the prongs of akey, by which bung shown in it is firmly screwedinto the part A. The part B has a vertical perforation, b', the lowerportion of which is counterbored and screwthreaded to receive a shorttube, b2, the opening in which registers with the bore b. Theelower endof the tube b2 has a thin strip of rubber, b3, secured around it andcovering the lower end ofthe tube, this acts as a valve to admit airinto the cask when the pressure within it is less than theatmosphericpressure and to prevent the flow of gases or liquids in theopposite direction.

The operation of the device so far as described, and as represented inFig. 1, is as follows: The bushing A is intended to be permanentlysecured in the cask. The hollow bung Bis screwed into 'the bushing A,after which the rubber globe C is forced into the bung B, where it willbe retained in place by the annular depression. After the cask isemptied and is to be refilled the bung B is withdrawn, the Cask iswashed and refilled, and the bung B is screwed back to its place. It isobvious that the vent-bore b and its valve at the bottom may be putthrough the bushing A, as shown in Figs. 3 and 4; but in the case ofFig. 3 it would be necessary to give the bung or bushing B a partialturn to elevate its flange a little above the bung-bush A to admit airfor the proper Ventilating of the cask, as shown in Fig. 3. In the formof bushing and hollow Fig. 1 it is preferable to make both the parts Aand B of metal and to have them united by a screw-th read, as shown. Inthe form shown in Fig. 2 the part I3 is indentical in construction withthe part B, Fig. 1, eX- cept that it is diametreally divided. In theforni shown in Fig. 4 the part A is left plain on the inside, as theordinary faucet-bushings are now made. The two-part hollow bung B may bemade of wood, plain upon the outside and driven into the bushing, as thecommon bungs now are, after the globe Chas been placedbetween the twopart-s, and in this case the globe maybe made of glass or some inelasticmaterial, which would firmly seat itself in the softer Wood as the partB is driven home. In case the bung B be made of wood and the globe C ofglass or inelastic material the vent-bore b and tube b2 should be in thebushing A. Otherwise the bore'b would be closed by compression when thebung is driven into its bushing. The bungs, as above described, areintended i'o be used as vent-bungs.

In Fig. 5 I have shown my bung,` constructed to be used as afaucet-bung. The only differences between the hollow bung B in thisfigure and the bung` B in Fig. l are that when used as a faucet-bung thevent-perforation b', tube Ir', and its valve are omitted and theinterior of bung above and below the annular depression which furnishesthe seat for the elastic globe C tapers to iit the tapered Shanks of theordinary faucets. I intend this form lobe used in combination with myvent-brings before described in the sume casi; or barrel.

In use the globe() will be forcedinto its seat in the faucetbushing B,and when it is desired to tap the cnsk the globe (lis driven into thecasl( by the end oI` the faucet, as the eommon cork now is. Alter theeask is emptied the ventbung l1 or 3 can be removed to wash the eask.rIhen the globe C is removed from the barrel through the bushing.

\Vhen B and (l are in use together, they constitute a bung. \Vheu thebung is used at the faucetopening,an(l Chas been driven inwardly out ofthe bung into the barrel by the faucetshank which is seated in B in theplace of C, then B becomes a bushingfor the faucet.

The faucet-bung illustrated in Fig. 5 is not claimed herein, as I intendto make the same the subject of a separate application.

What I claim as new, and desire to secure by Letters Patent, is-

l. Thehollow bung, the valved opening extending through the same, andthe stoppcrtl, compressed within the bung, i'or the purpose specified.

2. The bung B, having` vertical perforation If', the tube if, theopening ot` which t'orms the continuation of the said perforation, incombination with the spherical stopper C, substantially as set forth.

fl. The combination, substantially as specified, of the bushing A,screw-thrcaded externally and internally, the bung having avalve-opening vertically through it and thread-v ed externally to fitinto the bushing A, with the spherical elastic stopper (l to close theopeningin the bung,substautial ly as described.
